On nevada_49 using G++ from the CoolTools (gcc 4.0.2 from gccfss) I could work
around the issue by writing the following code right before the line "use
namespace KJS" in operation.cpp :

extern "C" {
#define INFINITY        (__builtin_inff())
#define isinf(x)        __extension__( \
                        { __typeof(x) __x_i = (x); \
                        __x_i == (__typeof(__x_i)) INFINITY || \
                        __x_i == (__typeof(__x_i)) (-INFINITY); })
}

These definitions should normally be included with "math_c99.h"...
